Abstract
Official abstract text for this publication.
A fill level measurement device is specified for determining distance of the measurement device and flow speed of a medium, which comprises a frequency-modulated transmission signal having a rising and a falling frequency ramp. The flow speed of the medium can be determined by the Doppler effect arising from the flow speed of the medium.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method, comprising: generating a frequency-modulated transmission signal, which has a rising and a falling frequency ramp; emitting the frequency-modulated transmission signal in a first direction perpendicular to a flow direction of a medium and in a second direction different from the first direction; determining a distance from the medium by evaluating the frequency-modulated transmission signal reflected by the medium and received by the antenna arrangement; and determining a flow speed of the medium by evaluating the transmission signal reflected by the medium and received by the antenna arrangement when the distance to the medium has changed by a predetermined threshold value over a predetermined period of time. 2. A non-transitory computer-readable medium on which a program element is stored which, when executed on a processor of a fill level measurement device, causes the fill level measurement device to carry out the steps according to claim 1 . 3. The method of claim 1 , further comprising: determining the flow throughput of the medium. 4. The method of claim 1 , further comprising: determining the flow speed of the medium when a predetermined number of distance measurements have been carried out.
